Abstract (en)
[origin: WO2004026576A1] The invention relates to conveyor belts, which have a laminate consisting of: i) a textile ply (1) with a first ply surface (11) and with a second ply surface (12); ii) a first synthetic material ply (2), which adheres to the first ply surface (11), is made of a thermoplastic material having a creep resistance vk of no greater than 0.005 at 30 DEG C, and which contains at least 70 % by weight of a thermoplastic having a creep resistance vk of no greater than 0.005 at 30 DEG C; and iii) a second synthetic material ply (3), which adheres to the second ply surface (12), is made of a thermoplastic material having a creep resistance vk of no greater than 0.005 at 30 DEG C, and which contains at least 70 % by weight of a thermoplastic having a creep resistance vk of no greater than 0.005 at 30 DEG C, with the provision that the quotient rv of formula (I), wherein VB represents the surface volume of the laminate, rho T represents the density, and GT represents the weight per unit area of the textile ply (1), results in a value ranging from 5 to 25. These conveyor belts can be joined to form endless conveyor belts via butt end connections.
